Nancy Blackett is a fictional character in nine of the twelve juvenile novels in Arthur Ransome's Swallows and Amazons series of books. She is a bit of a tomboy—acting as captain of the dinghy, Amazon and usually directing her friends in their various adventures. Nancy apparently has no real-world counterpart as an inspirational source for Ransome but appears to be completely the author's creation. Nancy is sometimes critically viewed as a subversive character for girl readers. The character appeared in a 1963 BBC television adaptation of Swallows and Amazons as well as in a 1974 film adaptation of the book.
